what if you used plastic with already crafted objects to create replicas that could be placed down as displays or decorations. ... like a iron sword surrounded by plastic blocks = Iron sword replica, which you could hang on a wall or shelf or something

I like this idea a lot, mainly because for some reason I find the plastic shovel very visually appealing. Go ahead and make plastic version of all the tools. The shovel and the hoe could be decent to bad, the axe, sword, and pickaxe can't do ****... But have more uses than diamond/ are indestructible. Actually that's fairly balanced. Plastic tools are really really shitty, maybe even shittier than wood, but they never break. What do you think? And no, it doesn't make much sense that diamonds would be more brittle than plastic, but this mod is powered by imagination.
